The Hex hatch was going off on the Williamson River when my colleague Doug Best and I were traveling through Oregon. The guys from Tailwater Fisheries called and said, “You have to check this out!” We also fished the nearby Wood River.

It’s pretty damn cool when you can throw, not just big but gigantic dry flies. Plus, this is a part of the country that is really only on the radar of a select group of anglers. The fish that Chris Renzullo landed is a good example of the kind of trophy fish one can target with these big bugs.


A big ol’ parachute Hex imitation is fun to cast, and watching a trout hammer the big bug is a blast.
